SPACING ,MECHANISM.

Application filed June 23,

To all whom it mwy concern:

' Be it known that HARRY ARTHUR Foo'r- Home, citizen of the United States, residing at -Harrisburg, in the county of Dauphin and State, of Pennsylvania, has invented certain new and useful Improvements in Spacing Mechanism, of which the following is a. specification, reference being had therein to the accompanying drawing.

This invention relates to typewriting machines and more particularly to a means for eflecting a variation in the spacing of the characters printed, without varying the uniform letter spacing movement of the carriage.

Viewed in another aspect, the invention relates to combined typewriting and adding machines of that class in which numbers printed by the typewriter are accumulated or added in a register, having uniformly spaced denominational members to which anactuator is successively presented by uni form letter spacing movement of the carriage, corresponding to the uniform spacing of the denominational members of the register. Viewed in this aspect, the invention embodies the idea of automatically effecting a variation in the spacing of the characters printed, while maintaining uniform letter spacing movement of the carriage and the consequent proper stepping of the actuating mechanism to successive uniformly spaced denominational members of the register.

In the accompanying drawings Fig. 1, is a vertical sectional elevation of so much of an Elliott-Fisher billing machine as is necessary to understand the application of my invention thereto.

3? Fig. 2, is a front elevation of the same 40 machine with parts omitted and others broken away for clearer illustration of the essential construction.

Fig. 3, is an elevation of the upper end of the type bar, showing the type head and the arrangement of the type thereon.

Fig. 4, is a plan view of the fragmentary machine, and

Fig. 5, is a diagrammatic view contrasting the two spacings of quantity and money values and showing the cam which controls the character of spacing of the printed record.

Before proceeding with a detailed description of the mechanism, an understand- 1919. Serial No. 306,102.

ing thereof may be facilitated by a brief explanation of the general idea involved The Elliott-Fisher billing machine 0t commerce is a flat platen typewriter, in

ated from the keys as they are depressed to print th numbers. As successive digits of a number are printed on the work sheet, the carriage advances uniformly to present the printing point of the machine at successive uniformly spaced positions. The digits printed will thus be uniformly spaced and as the spacing of the number wheels corresponds to the spacing of the digits, said number wheels will be successively operated to accumulate, in the proper denominational positions, the values of the digits as the number is recorded.

Sim-e these machines are designed to compute values of various kinds. notably. quantit and money values. the are equipped with a variety of adding. devices, or registers, which is that part of the mechanism operated by the actuator and includiuga series of number wheels.

A quantity register has a series of number wheels uniformly spaced throughout the length of the series, because quantity values are expressed by digits which are usually uniformly spaced. Money registers. however, have two co-axial series of number wheels, the spacing of each series being uniform, but a space being allowed for the decimal point between the two series. Obviously, the purpose of this arrangement is to accommodate the decimal space which must be provided between dollars and cents in the printed number, as fully explained in Patent No.922559 toLaganke and Smith.

The money registers are equipped with decimal trips which effect automatic spacing of .theearriage over the .decinialspace, so that fwhen ithe decimal ositioniis reached the spacing movement 0 the carriage and of the actuator are exaggerated or doubled. T-h'is is obvio'u's'lya variation in the spacing movement-ofthe machine.

The invention with which we are now concerned has for its object, to permit/the use of a quantity re ister, having a continuous series of uni ormly spaced 'number \rl eels, fo r the computation ofinoney values printed, in the iisual uzay, with afdecimal space between dollars and cents. ;;T;he,.co nflict between the uniform spacing require-,

ments of the uantity register and the .non-

uniform 'spacing requirement of a money value record, I of spacing the carriage uniformly tor one purpose and of simultaneously spacing said carriage non-uniformly for other purhas furnished the underlying problem; of the present invention. Qne solution of,

that problem embodies provision for scour in non-uniform spacir gof the characters printed, without necessitating any disturb- ,arice of the uniforiuspaeing movement of? the carriage, which is necessary ,to present the actuator to successive uniformly spaced number .wheels .as the -;digits are printed with the decimal space, ,or, in ,wha t., .may be said to be, non-umformlyispaoed relation. The desired end ,is obtained by the simple expedient of placing the upper case number types in off-set position, one space to the rightof thenormal printing point of the machine, and in prov ding an automatic case shift, which, when the actua tor reaches the ,number wheel representing tens of cents, will automatically provide'for the print-lu of ,upper case characters to the right of a decimal space which the QE- setting of the characters provides whenthe keys are depressed to print tens and units of cents in off-set position.

This will be seen to constitute automatic changing or shifting of the printing point of the machine independently of and without. wiry-in; the uniform letter spacing movement of the carriage.

With the foregoing general idea of the .problem and its solution, we may now proand the obviousimpossibility key, its type bar 6, and the intermediate conneqtions are --clearly,sho wn lip the drawingsa i ht the upper wag-ii eadlr type bar ismounted a shiftable type head 7, having upper and lower case types 8 and 9, and a trigger 10 which extends beyond the end'of the "bar. Normally, the -operation or the keys will swing the type bars-"toward the platen and cause the uppermost or lower case type to ymint. When it is desired to print'upper case characters, the depression of a shift key ll rocksa trip sha't 12, to; depress an arm l3 exten ded therefrom and rry ng a his 1 331115, t todrop thetrip l t fron its,normal pos ition,

I,

The described character of case shiit is usual and Well knosvn but its purposehas aliyays been, to cause either-Hot twoytype 'carried by tliesame type bar tol e presented at the single printing point of the machine so, that the printing of either character would,havemoetfeet whatever on the sp re: ing ofthecharacters printed in agiven line,

' Such indeed, is still. the general purpose. oif

the case Shit ft mechanism of a machine embodying myinvention, but in such machine a difl'ereut. ;purpose is subserved with respect to the ease shift of the bars carryin-, digit typeand operated from the digitheys. Thus, as shown, in Fig. 3, for example, the tXPt'dICZUlS-flf the digit printing bars are equipped with upper and lower (:pilfictligfji type 8 and 9?, These typeare or may he identical,'exce-ptthat while the lowercase type 9 is arranged to print the digit .torins stance 9, at the normahprinting point ofthe machine, the upper case type S is mounted on the. head with the digit, 9 for instance, 10-- cated in such volt-set relation to the lower. case digit that it will printto theright of'the normal printing point when the type bar is thrown down. This will be clearly understood by reference to the diagrammaticrecord shown in Fig. 5.

lhe upper row of 9s are printed in the usual uniformly letter spaced positions by successive operation of the nine key, print,- ing from the lower case type. The first i-ve of the lower row of 9shave oeen similarly printed but prior to the printing of the-last two 9s the depression of the trip 14;: has caused the shift of the type head antl the 1' values, without in consequent printing of these two characters incojfset position so as to leave adecimal.

space between dollars and cents, not\vi thstanding the fact that the letter spacing ing of the entire line of digits, has been uniform. In other words, the two rows of 9s in Fig. 5 show the digits spaced as usual in making records of quantity and money any way effecting or changing the uniform letter spacing movement of the carriage, which, y reason of my invention, is maintained regardless of which character of printed, record is deisired.

On the contrary it is highly desirable to secure a very compact arrangement of the registering mechanism, notwithstanding the desirability of having the printed record show the decimal space at the proper point.

For illustrative purposes there is shown in Fig. 2, two quantity registers in close relation. Each of these registers exhibits a se ries of digits in uniformly spaced denominational positions as indicated, for instance, by the upper row of digits in Fig. 5. Obviously, if the. Wheels carrying these digits are operated in succession by the actuator 18 pre sented to them by successive letter space movements of the carriage, such letter s ace movements must conform to the uni orm spacing of the number heelsfand, if, the printing .point of the, machine similarly advances across thecolumn, the digits must be printed in uniformly; spaced relation.
